If you add information to an article, be sure to include your references, as unreferenced facts are subject to removal. Since not all articles are about events or people, and may instead be about features of Scratch, some articles may have no references - and that is okay. However, when an article does require references, it is best to use inline citations so that other editors and readers can verify the information you add. Also, make sure that every source you use is trustworthy.
The easiest way to create an inline citation is with a footnote. You can create a footnote with Wiki markup, by adding ref tags around your source, like this:
- <ref>Your Source</ref>
If you're adding the first footnote to an article, you also need to make sure that there is text that tells the software the Scratch Wiki uses to display footnotes. That text will look like this:
That text should be immediately below the section heading ==References==. If that section does not exist, you will need to add it (both the heading and either the "Reflist" or "references" text above). Place the new section near the bottom of the article, just above the "External links" section (if that exists).
Once you have saved your edit, the ref tags will convert your citation of a source into a footnote reference (like this one), with the text of the citation appearing in the References section at the bottom of the article.
If the citation you are placing between the ref tags as your source is a link to an external website, place the website address (URL) within single square brackets along with some text, which the reader will see as a link. For example:
- <ref>[http://scratch.mit.edu/article_name.html Article on the Scratch Website]</ref>
Although material that is from external websites is a common reference source, the Scratch Wiki has no preference for online sources. If your source is a book, journal, magazine, newspaper article, documentary or other source, then you would place identification information about that source between the ref tags.
If you respond better to visual information, you may find the guide below useful.
| Two separate citations.<ref>
Note<ref group="note">Take note of this</ref>
<references group="note" />
| Two separate citations.|
Multiple citation use.
Please see Help:References for further instructions on writing footnotes, as well as an important format to follow.
Many Scratch Wiki articles have a separate section called External links. This section is for linking to websites with significant and reliable additional information on the article's topic. If an article already has more than a few links in the "External links" section, and you're an inexperienced editor, you probably should suggest any new links on the article's Discussion (talk) page before actually adding one.
To add a new external link, just type, inside a single set of brackets, the full URL for the link, followed by a space and the text that will be visible. For example:
- [http://www.example.com/ Official website]
will display the following, whilst linking to the full URL:
